Tiger Woods PGA Tour 12: The Masters

To unlock a HAMMERhead Prototype Club you will have to unlock all other clubs of that type. For example, to get the prototype driver you must unlock all other drivers in the pro shop.

Most clubs are unlocked through gaining Sponsor Levels with the 6 main sponsors (EA Sports, Cleveland Golf, Taylormade, PING, Callaway, and Nike.) There are a few clubs, however, that are unlocked through the Sponsor Challenges that are made available before each tournament (Mizuno Wedges for example.)

In order to unlock ALL HAMMERhead Prototype Clubs You will have to reach Level 4 with all six of the main sponsors, as well as complete the few challenges which award clubs. To see which clubs you still need to unlock a certain prototype you can use the search option in the Pro Shop. Just set the filters up like this:

Category: Equipment
Subcategory: Drivers/Fairway Woods/Iron Sets/Wedge Sets/Putters (whatever you are focusing on unlocking)
Brand: All
Boost: All
Status: Locked
Level: All
Owned: All

When you select a club it will tell you how to unlock it, be it by Sponsor Levels or Sponsor Challenges.

You can also purchase level 4 of each sponsor by selecting them and pressing (LB) to open the store. To purchase all sponsors will cost you about $20 so I recommend playing though a bunch of seasons and unlocking as many as you can while working on other achievements and use this as a last resort.

*ATTN*=> Purchasing level 4 sponsorships prohibits unlocking the "Pin Collector" achievement, by preventing gaining the "Prototype" pin for legitimately unlocking the prototype clubs. Thanks BillJones0302 for the heads up.

If you have purchased Sponsor levels and it has prevented you from getting "Pin Collector" you can go to System Setings > Memory > Hard Drive > Games > Tiger Woods PGA TOUR 12. Now delete any items named "Tiger Woods PGA TOUR 12 Sponsors" from your hard drive. (You can redownload them again later if you wish.)
